Abstract

PC-cell-derived growth factor (PCDGF, progranulin) is a novel autocrine growth factor that is overexpressed in human breast cancer cell lines. We have examined immunohistochemical PCDGF expression in 206 paraffin-embedded human breast lesions and investigated its association with clinicopathological variables. PCDGF staining was observed in breast carcinoma, whereas it was almost always negative in benign breast epithelium. PCDGF expression was more common in invasive ductal carcinoma (80% cases positive) than in invasive lobular carcinoma (53% positive). PCDGF staining was almost never observed in lobular carcinoma in situ. Ductal carcinoma in situ expressed PCDGF in 66% of the cases, and this expression correlated strongly with nuclear grade. Similar correlation was observed between PCDGF expression and histologic grade of invasive ductal carcinoma. Average Ki-67 index of PCDGF-negative/weakly positive invasive carcinomas (30.3) was significantly lower than that of strongly PCDGF-positive tumors (48.8, P = 0.01). A larger percentage of tumors that expressed PCDGF with a staining intensity of 2+ or 3+ were p53 positive (44%) than were PCDGF-negative tumors (25%), P = 0.02. PCDGF expression was independent of c-erbB-2 overexpression and of ER and PR status. Our study provides the first evidence of high incidence of PCDGF expression in human breast cancer in which it correlates with clinicopathological variables such as tumor grade, proliferation index, and p53 expression. These characteristics, as well as the virtual absence of expression in benign breast tissue, suggest an important role of PCDGF in breast cancer pathogenesis and make it a potential novel target for the treatment of breast cancer.

Tissue samples

Two hundred six nonconsecutive archival formalin-fixed, paraffin-embedded human breast lesions from 152 patients were obtained from the University of Maryland Department of Pathology files and from the National Cancer Institute of Canada-Manitoba Breast Cancer Tumor Bank of the University of Manitoba, Winnipeg, Canada (kindly provided by Dr. Peter Watson). The 152 tissue blocks examined contained the following lesions: 27 ductal carcinoma in situ (DCIS), 12 lobular carcinoma in situ (LCIS), 124

PCDGF expression in human breast tissue and its association with histologic type

PCDGF expression was observed in 128 of 206 cases (62%; Table 2). Most benign breast epithelium was negative for PCDGF (25 of 26 cases, or 96%), as were most LCIS cases (11 of 12, or 92%). However, the majority of malignant noninvasive and invasive ductal lesions showed PCDGF expression. The difference in PCDGF expression between benign/LCIS and intraductal/invasive carcinomas was statistically significant (P = 0.001). Eighteen of the 27 DCIS (67%) and even a higher proportion of IDC, 99 of

Discussion

Our studies with human breast cancer cell lines have indicated the biological importance of PCDGF in breast cancer tumorigenesis,8, 9, 10 thereby warranting the investigation of its expression in archived pathological samples. This is the first report describing the expression of PCDGF in human breast tissue. We have shown that PCDGF is almost never expressed in benign breast epithelium. PCDGF expression was not seen in lobular carcinoma in situ, whereas the majority of invasive lobular

      In fact, other pathways are also activated by estrogen. In addition, the PGRN expression is not estrogen (and ER)-dependent, because the PGRN overexpression is also seen in breast cancer in the absence of estrogens [38,47]. The central role of estrogen in the initiation of mechanisms involved in the development of breast cancer has led to the use of anti-estrogen therapy in the clinic to breast cancer treatment [48].

      Both tissue and blood tests have been developed for determining GP88 expression in tumor tissue and measuring GP88 in biological fluids. Use of these tests has shown that: (1) GP88 is present in breast tumor tissue whereas it is not present in corresponding “normal” breast tissue37; (2) Increased expression of GP88 in estrogen receptor-positive breast adenocarcinoma cell lines is associated with estrogen independence and resistance to anti-estrogen therapy and aromatase inhibitors,38,39 whereas in human epidermal growth factor receptor 2-overexpressing BC, GP88 stimulated human epidermal growth factor receptor 2 phosphorylation and conferred herceptin resistance40; (3) Increased tumor GP88 expression measured by immunohistochemistry in breast tumor tissue is an independent predictor of recurrence and is associated with poor outcome41,42; and (4) circulating levels of GP88 are measurable by enzyme immunoassay (EIA) and, compared with healthy individuals, elevated GP88 blood levels are found in patients with BC.43 Because high GP88 tissue expression is associated with poor outcome including increased risk of recurrence and mortality and because GP88 stimulates hallmarks of metastasis,44 we have hypothesized that GP88 circulating levels could be used in patients with MBC to monitor disease status.

      We identified Ripk1 as our top hit because 1) it was one of the most effective up-regulators of PGRN (in the secondary screen, a mixture of four Ripk1 siRNAs increased secreted PGRN by >2-fold (Fig. 1C); 2) Ripk1 is highly expressed in the brain; and 3) there are many tools available for interrogating Ripk1 function. FTD patients have about half the normal level of PGRN, and many cancer patients have supraphysiological PGRN expression (21–23). Therefore, we wanted to increase PGRN from the disease range (half) to the normal range, a factor of ∼2.
